Hey all,

For creating images I use an pre-scripted textfile in which the light settings
are definded.
Now I need to setup some global settings which can not be setup within this
file.
The script of this file ist written below.
Is there any way to define global settings within an .ini file. Or is there any
command wihtin the script I can use. At my point of view it is not possible to
define global setting in this file, because this commands are read after the
model is rendered...

Thanks for any help!!

Maybe you could elaborate a bit on the workflow you are using, as I
don't think I completely understand what exactly you are doing.
(If you're struggling to explain it in English, feel free to explain it
in German instead.)

The only part I do understand is that you're using some other scripting
language (which one? I don't recognize it) to generate snippets of
POV-Ray scene code (how are they passed to POV-Ray itself?).

My first guess is that POV-Ray's `#include` statement is the key to
whatever you're trying to do.
